Hello all, i am planning to get a new phone by trade-in W580i,(Yeah, i know it has everything i wanted, but, i want to trade it for some reason.. )

1. Brand. - Samsung (or you all can suggest brand thats last longer battery than Samsung?)
2. Budget. - around RM400+-
3. Specs. - GPRS, MMS, Camera, Bluetooth, MP3 Ringtones, MOST IMPORTANT is compatible with Opera Mini 5.1, lol..
4. Type/Size. - any

I have two models in my mind, which is E2152 and S3600. E2152 is cheaper but it's in black which is not really i like unless theres someway to change the cover colour.. S3600 is ok, but i am worry about the fragile or keypad not response later..., any opinion on this or suggestion on other models?

Many thanks in advanced.
