Have read some posts about the 2.1 update wiping out the data, etc. and have some questions about readying my Hero for the 2.1 update: 1) HTC Sync won't install on my system ... how will I install the 2.1 update? 2) I'm not interested in saving my SMS, MMS logs, call history, etc. ... only a GMail acct is set-up (to activate phone, etc. not used for email) ... all my contacts are "Google" type: do I need to do any sort of backup on this info? How will I get it back again? 3) Not using any widgets but have customized the home pages ... will all that be lost? Same with system settings? 4) Have just a few apps, all are freebies, minimal if any data (specialized settings, etc.) associated with these apps ... anything I need to do here? Thank you.
