That sounds like a device issue, the network updates couldnt cause the phone to react like that. I oved the Tilts a.d think they were the best winmo phone for me. The tilt device have had it’s defects and issues since it was first released. I have had three. One out of three worked excellet, volume was great, processing was okbut not as choppy as the one before it. Finally my tilt was laid to rest in pieces in Cellphone SIMetery. When is your next upgrade, why not consider android, it processes more smoothly from what ive experienced. Or if your phone is warranteed, see if you can get a different phone since three in a row were not good.
