Looking at the same deal, how you getting on with the N97?
After reading couple reviews, i thought it was going to be a bit shitty.
It arrived today and my brother opened it while i was in work and said that he thought it was crap!
I've played around on it for couple hours now and starting to quite like it! it's alot more updated than my previous sony erricson phone I had. For the £35 a month though, it comes with 600 more mins, unlimited internet & £50 cashback. considering i've been paying £40 on the exact same contract with orange that i just cancelled it's worked out pretty well for me!
I think you're asking alot though to get top phone and nice cashback tbh!
