Problem when getting off a phone call..?

[beefillups]

(Keep in mind this has been happening since 3.0 beta 4 on my 3G))

I used to own a White 16GB 3G and ever since I had 3.0 beta 4, I've had this problem. The problem is, every time I hang up from a phone call, none of the iPhone's buttons work for like 30 seconds. After I hang up, I can change the menus (ex. Favs, Contacts, Recents, etc) but I cant turn off the screen or go to the home screen.

It's been doing this since 3.0 beta 4 on my 3G and now I'm currently running 3.1 Beta on my 3GS.

Anyone else having this problem?

Anyone?

I notice this with my EDGE phone, mostly with outgoing calls. After I end the call, I seem to be stuck on the contacts/favorites screen for ~10s before the home/sleep button work again.

This only started after updating to 3.0
