I am looking at purchasing a new smartphone (the iPhone is NOT going to meet my needs unfortunately). I am with Cingular and looking at the Blackjack or the Cingular 3125. I currently have a Treo 600. Has anyone used the 3125? I have looked at reveiws and such but wanted some your opinions. How easy is data entry (adding calendar items, contacts, etc.) Phone reception, baterry life, any 3rd party add-ons. etc.
