Here is my situation: I currently have a iPhone which sync with a PC with windows 7, and I'll be going to study overseas in Australia. Since my PC is getting old and slow, i decided to leave it behind and get myself a new iMac when i settle down in Australia. The problem is, i have a lot of SMS as well as apps data (I know i can reinstall the app, but what i really need is the data within the apps) that I want to keep, but there won't be a time where i have both computer at the same place at the same time. What i'm worrying is the new mac will ask me to overwrite my iphone. Is there any way to avoid this? i really need my SMS... I know there are a lot of similar topics, I've done my homework but still couldn't find a complete solution. What do you guys suggested?
