Does anyone with you upgrade to an unlock GSM upgrade patch experience this problem?

1. my treo keep on reseting itself for no reason after the upgrade.. it sometime just sit idlely on the table and reset itself...

2. the phone voice quality is worse than b4.. the voice will sometime become soft and then loud again.. and the dialling tone from the speaker is so much noisy than last time..

so far this is the 2 things that bother me after the upgrade.. does anyone else experience this?

How can i move back to the last version?
