Been using the phone all day and never used the device lock and never had a freeze.
The only thing that ain't perfect at this point is PhoneAlarm's integration. Overall the program is great, but the new betas still have some significant glitches that keep recurring in different betas.
I swear I'd pay for a good program that did as much as PA does with a little more stability and consistency. (That means being able to monitor incoming calls, voicemail, email and sms's using different profiles that can be switched based on time or event scheduling. Is that too much to ask for?
)
