I connected my iphone 3gs to recently updated version of itunes today. Have about a dozen or so apps which it then, without warning, sync-d to my pc. Fine. But of course its taken the apps off my phone and put them onto my pc. So I put them back onto my phone, and now not only have I lost all data in my apps (i.e. financial info, save point in games etc) I have lost the upgrades I had paid for. So for example the 'talking tom cat' app, my kids favourite, I'd downloaded for free then paid 59p to upgrade to full version - but now I am back to the basic 'free' version after all this sync-ing. So - what is the "right" way to back up apps? I read somewhere that you do loose the data but can't you back up without taking them off the phone? Also - is there any way to get back the 'upgraded' version of the tom cat app? (its not about the 59p, but next time it could be ££s). Any help greatly appreciated!
