N 81 RIP?

My Nokia N-81 is starting to show signs of senility. The phone seems to be acting up wierd. I am scared about giving it to the Nokia Service Centre as they sometimes stock it for 2 months and then decide that nothing can be done about it. The cost of repairing the Nokia phone may be 60% the cost of the phone, and that data is not too appealing to me to repair it.

Maybe I need to look at more phones in this segment, as a back up. I'd like to have my hands on the i-phone, but the cost of the iPhone is what draws me back. All said and done, I have to start researching on models that are similar to the N-81, as I fear its days are numbered. Lasted 20 months(Make that 18, it slept for 2 months in a Nokia Service centre).
