I am traveling for the next week and would like to update the firmware on my iPhone 3g... My phone syncs with my Macbook (which I left at home for this trip), but I do have my corporate Dell laptop with me (I am on a business trip)... I have connected the 3g to this laptop before but only to charge the battery while I listen at my desk... If I use the Dell to update my phone: -Will it overwrite my contacts on the phone? (this would be bad) -Will all my music and videos and stuff be wiped from the phone? (also bad) I just don't feel like waiting a week to get the new FW... Tired of e-mails and text taking forever to input unless I reboot the phone! Thanks!
