Prepay iPhone safe to upgrade to 2.0?

[Pekkle]

I know once the firmware is upgrade you will need to reactivate the iphone. Now, since I have prepay, will it mess up on activation? Will I be able to go back to 1.1.4? I never downloaded the 1.1.4 before, I have 1.1.3 that came with the 16gb iphone. will I be able to go back to 1.1.3 or 1.1.4?

No problems as long as you back your iPhone up.

I had no problems with mine

Good Luck
