is there a way to make text bigger on text messages or is there a way to save messages on my computer so i can print them on my iPhone 3

Zoom will enlarge anything on the screen, simply double tap with three fingers.

To turn Zoom on/off go to Settings > General > Accessibility > Zoom.

Large text may also work for you.

Settings > General > Accessibility > Large text. Select the font size that works best for you.

Printing or accessing text messages via the computer is not support. Google it and you will find options.

You can also copy and past the content into an email to send to yourself. Then that email could be printed out.

Hello

I want to enlarge the text on my messages and have the I Phone 3, on IOS 4.2.1 and I have checked in settings>General> - but the Accessibility is not there ..

How do I get to access this on my phone ?

Mine is not the 3GS just the 3G

Thanks

If the feature is not there, it would indicate to me that it is not a part of that version of iOS.

Since 4.2.1 is the end of the line for the 3G, the only way to get larger text would be to upgrade to a newer device.
