I recently got the Nokia 6230i having previously had the 6230 model (which met an unfortunate end in a glass of vodka!)
Anyway while I was happy at the time with my 6230 ive found the 6230i a greatly improved model, the battery life is much better, i generally get about 6 days from it. The camera and graphics are vastly superior, and like all Nokias it is really easy to use. There are loads of other functions which i still have to figure out such as the "push to talk" function which i have no idea about but I have to say ive been very pleased with it so far.
