Anyone else got it? I moved onto contract back in Novemember. Searched high and low for a contract that suited me and found T-mobiles Flex packages very appealing. Went for their £25 one. Originally i wanted the D900, but they didnt have it in stock and i couldnt afford to live without a phone(ran out of money on pay & go and didnt want to have to put more on). Just as i was about to leave they offered me the Z560, i had a fiddle with it and instantly adored it. Its pritty much the same as the D900, except clam shell.
It has full HSDPA access, for which i pay £7.50 a month and it works a treat, its fantastic for when your bored. Only down sides i have found are the battery life which gets drained very quickly(few days if you are a heavy user of internet/calling/texting) but you get 2 with it, so it rarely works out to be a problem. Second down side is the fact that if you are playing musi through it, you cant do anything else. Mate with the D900 can 'minimise' the music player and use all other facilities on the phone at the same time. Trying that with the Z560 pauses the music.
Aside from that, cant fault it. Any other fans/critics?

edit: One other thing, the samsung phone suit/PC software is a dream to use, really really well thought out & easy to use.
