Hello all, I have just taken out a new contract deal through the carphone warehouse with o2. I decided to get the N96, on an 18 month contract (the phone was free with the contract). Now upon receiving the phone, I have noticed the phone lags a little, this is my first Nokia (I normally get the Sony Erricsons) and I am not impressed. Now I am wondering if I will be able to return the phone for a direct swap to the SE C905. The only problem is that I have put my sim card in the phone, unwrapped the battery, unwrapped the charger and have used the phone for 2 days.
