Well, my 2 years of iPhone use are slowly but steadily coming to an end.
It seems it's battery is wearing down as well. (Coincidence?)
I can't say it's all bad. The huge variety of apps is nice at times, and the Twitter app ("Tweetie 3.0"?) is neat.

However, the lack of multi-tasking hurts and it's rather weak (fixed in 3GS and the new one, I have 3G).
Though, I find the new iPhone's look to be nice.
Worth signing yourself to deal with iTunes and aIds for 2 or even more years? Hell, no. But nice nonetheless.
With that in mind, I am looking forward to switch. BlackBerry contracts in Latvia have gotten decent, so I might as well get one of those finally. Been wanting to get a nice QWERTY phone for a while now.
