The Omnia is absolute Wank. A great phone to look at... and it's Shiney.... The Positives stop after that. I've had numerous problems with memory, battery life, the screen freezing, crashing randomly, the touch screen is dire.. clicking links on the net is hopeless, you have to open a new tab every time you do. Stylus broke after a month and it won't update.
I've been through 3 Omnia's with recurring problems, the major of which has been the memory stating it's full when it's not. 8Gb standard + an extra 8Gb memory card, and it still thinks it's only got 90Mb to play with. Can't store any music on it what so ever without it spagging (there's no better word...), bluetooth struggles with simple pictures and any downloaded programs I have (endorsed by windows) hate the sodding thing.
Gah.. It's WANK.
Rant over , I wish you all the best, i've probably had bad luck with them. (also good luck explaining to other people what phone you have, no one.. ever.. has heard of the omnia... i've had to say "It's samsung's attempt and an iphone" for months now)
