hi people, im a noob to the N900, so this may sound stupid but ill ask..... your all talking about upgraded firmware, can i do this with nokia pc suite's inbuilt upgrader thing ? i dont even know how to flash my phone, it sounds complicated and as ive only had it 3 weeks i dont want to brick it by trying to reflash. also would reflashing it myself invalidate my warranty ? my phone is a UK one and is running version 2.2009.51-1.203.2 unless im looking at the wrong thing ?
