hi guys, this just happened to me minutes ago, i was playing an app, suddenly all of a sudden my screen zooms in, even when i go to home page, my icons are all big.

has anyone experienced this before? have i accidently pressed anything wrong?

tried to double click the screen, it doesnt zoom out. everything is big now. tried to switch off and restart, doesn't work also.

--------------------------------------

sorry found my solution from the internet. if anyone has the same problem in the future, double tap with 3 fingers.
anyone who doesnt have this problem can also double tap with 3 fingers to zoom in. 

Knowing that the latest Pwnage Tool 3.1.3 now supports iPhone 3GS
Does it solve the issue where people updated to 3.1 and bricked their 3GS?
Will everything be fine by just restoring to the custom firmware using this Pwnage Tool?

this is what i did, for both my MBP and XP (via bootcamp):

transfer your songs to match at least 95% of the original contents in your previous windows to the MBP - crucial to ensure that iTunes doesn't erase the contents on your current iPhone.

then synchronise the iPhone once. iTunes should make a new backup on your MBP now.

yes.

yes.
erm, all the four iPhones i have had, still have the saved games and applications well (for example, i didn't have to re-log into my beejive)

anyway if it does backfire, you can always restore from your windows iTunes no?
