Just to clear things up, the data error is caused by 1.7 right? I flashed 1.7 multiple times yesterday night and had no data aswell as receiving hands free activation notifications.
This morning I flashed back to 1.6.2 and everything is fine and dandy again.
See post #1, specifically the "requirements" note
The data problems and handsfree problems are caused by your phone being unable to verify it's PRL, PRI, and profile. You'll also likely be noticing less than stellar performance because your phone is constantly using resources to achieve the verifications i mentioned above. The fix is to go through the process of updating your baseband to the newest radio. That process is described in length in the root sticky.
