I recently updated my Verizon 8330 from .77 to .131. I now seem to have a lag when answering calls. It takes a sec or 2 for the connection to be made after I try to answer a call. What's up? I don't remember this with the old OS. If I need to go back to .77 I will - I haven't found anything that .131 seems to do much better than .77 - I just wanted to do the upgrade and see. If I do need to go back, how is it done?
