My mates' got an N70 on Orange, mine's on Voda... I actually quite like their side bar compared to my active standby - however, my N70 allows you to assign shortcuts to up, down, left and right on the navi key, where as his only allows up and down!
Mine has a few niggles - isn't amazingly quick when browsing gallery, and has crashed a handful of times but nothing a firmware update won't fix when the next one's released...
