Ok, so let's say you want to get 2.2 on your phone by using one of the various hacked 2.2 ROMs. Common knowledge is that when you do your Titanium Backup restore, you do not select "system data" else you will have problems. Very well... but what are the alternatives for getting this system data converted? Some specific questions: 1) I know contacts, SMS and saved wifi APs are part of this "system data". What else that one might care about? 2) Is doing an export to VCF and then import sufficient to get your phone contacts back? Is this restore perfect? Or is anything lost? Images, groups, all data fields, etc? Please don't suggest syncing to Gmail... I've experimented with this and cannot get it to work in a way I like. 3) Any separate way to backup and restore saved wifi APs? I have a ton of saved passwords that I don't remember and it would be a pain to track down the person who knows again. 4) Are any of the individual "system data" elements actually ok to back up in 2.1 and then restore in 2.2, alleviating this problem? Contacts? Wifi APs?
