phone freezing?

[lawsofpower48]

has anyone else experienced their epic4g's freezing? my wife and i have an epic...and ones rooted, the other is not..... our phone actually freezes and we need to restart? or there were times when i didnt even know that my phone did not work until i tried to make a call out.... the screen turned on fine, but it kept saying "dialing"....then i noticed that it was sort of frozen.... so when i restarted, a bunch of txt msgs, voicemails, emails all came at once.... then ppl called me and told me my phone was off??! happend to me 2 times already (rooted one)

my wife hadnt rooted her phone, and her phone has missed txt msgs, missed calls...or the phone just doesnt turn back on after idle?!

anyone else experiencing problems like that?thx
