Q1. I can't find iSignature in the global Settings application. How do I enter my signatures?
Starting with version 2.0, the signatures are created in the application itself, not in the global Settings application. The items that you see when you launch the application are the signature entries that have been pre-populated with examples and instructions for using the application. To create your signatures, simply overwrite the pre-populated contents with the contents of your choice.
To create/edit a signature, tap the 
icon on the
right edge of each signature item in the main screen. Then tap the field that you wish to change. The "Name" field is what
is shown on the main screen, the "Contents" is the signature that will be included in the mail composition window, and "Image"
is the optional image to include below the "Contents".
To send an email with one of the signatures, tap the main area of the appropriate signature entry in the main screen. That will pop up the mail composition window with the selected signature.
Q2. The default signature shows up below the signature that I select with iSignature. Is this a bug?
No, this is not a bug. The current OS does not allow third party applications to access the default signature. Therefore, before using iSignature, please clear the default signature. If Apple ever provides a way for developers to access the default signature, iSignature will be udpated to automatically handle this.
Q3. Is there a limit for the number of lines that a signature can have?
No, iSignature does not place a limit on the number of lines in each signature.
Q4. Can I enter special characters such as curly braces, ampersand, yen symbol, bullet, etc.?
Yes. iSignature supports special characters. In fact, you can use any character that you would enter into a normal email.
Q5. Can I use HTML tags in the signature?
Yes. iSignature supports HTML tags. For example, the below HTML code will generate the email shown in the HTML Signature screenshot.
<b>Bold Text</b> <i>Italic Text</i> <u>Underlined Text</u> <font color="red">Colored Text</font>
Q6. Can I include a picture in a signature?
Yes. iSignature allows you to assign any picture from your device's library of photos to each signature. See the Picture Example screenshot for a signature with a picture. The corresponding signature configuration screen can be seen here. Note that due to speed and size considerations, large images will be scaled down to a maximum resolution of 640x480 pixels.
Q7. What is the "Use In-App Mail" Option?
The option controls whether the mail composition is done within iSignature (i.e. "in-app") or in the Mail application. In-app mail is suitable for most situations. However, you may want to compose the mail in the Mail application if you wish to read emails before or after sending your email, compose your mail by copying text from existing emails, use a signature in a reply (see below for more details on this), etc.
Q8. Can I use iSignature for reply/forward emails?
Yes. The process to do so is as follows. In all cases, the "Use In-App Mail" option should be set to OFF.
- OS 3.1.3 and earlier
- Initiate a reply/forward in the Mail application.
- Return to the home screen by pressing the home button.
- Open iSignature.
- Tap the desired signature's "envelope" icon.
- OS 3.2 and later (Method 1)
- Open iSignature.
- Tap the desired signature to copy the signature contents into the clipboard.
- Return to the home screen by pressing the home button.
- Launch the Mail application and initiate a reply/forward.
- Paste the signature into the mail composition window.
- OS 3.2 and later (Method 2)
- Initiate a reply/forward in the Mail application.
- Return to the home screen by pressing the home button.
- Open iSignature.
- Tap the desired signature to copy the signature contents into the clipboard.
- Return to the home screen by pressing the home button.
- Launch the Mail application and paste the signature into the mail composition window.
Q9. When replying/forwarding, the From: account is set to my default email account even if I had selected a different account. Is this a bug?
No, this is not a bug. The current OS does not allow third-party applications access to the user's email account information or the email being replied/forwarded. The current OS pre-populates (forces) the From: account to the default user account for emails generated/replied/forwarded by third-party applications. Therefore, you will need to set the From: account after you select the desired signature in iSignature. If Apple ever provides a way for developers to access the email accounts, iSignature will be udpated to automatically handle this.
Q10. My signature picture is displayed as an attachment instead of as an inline image. Is this a bug?
No, this is not a bug. Different email clients handle images differently. Moreover, certain email clients, such as Thunderbird, display images differently depending on the signature content. For example, if your signature does not contain any HTML tags, Thunderbird will display the image as an attachment whereas if your signature includes any HTML tag, even an empty tag such as <b></b>, it will display the image as an inline image. Thus, you might try including an HTML tag in the signature to see if this forces your email client to display the image inline.
Q11. My signature picture is not displayed by my email client. Is this a bug?
No, this is not a bug. In some configurations some email clients, most notably Outlook 2007, refuse to display inline HTML images. If you experience this and cannot successfully configure your email client to display inline HTML images, please use the following work-around.
- Place your signature image on a publicly available web server.
- Unselect the picture in iSignature.
- Place the following at the end of your signature contents field:
<b><img src="SIGNATURE_IMAGE_URL"></b>
where SIGNATURE_IMAGE_URL is the URL of the signature image on the web server.
Q12. My signature picture shows up huge in received emails. Is iSignature enlarging it?
No, iSignature does not enlarge pictures. iSignature only downsizes the sizes of images that are larger than 640x480 pixels. Otherwise, it leaves the image size unchanged. If your picture is getting enlarged, it is probably because you used iTunes to upload the picture to your iPhone or iPod touch. To prevent this, email yourself the picture image and save it from the Mail application on your iPhone or iPod touch. That will ensure that the picture isn't enlarged and will show up in the correct size when used for signatures.
