Handy tip about setting it to 2G only. I'm finding that Vodafone's 3G coverage isn't as good as 3's where I am and a lot of the time I get the dreaded 'no bars and white cross' when the phone's set to auto. Switching it to GSM-only always gets me a signal in those cases.. ..back on topic - the 1500mah Hong Kong cheapo spare battery arrived today and it's currently in my phone. First impressions are good - it did appear to take longer to charge fully and it hasn't dramatically died or anything. I'll know how it compares to the proper battery this weekend when I'm out and about with the phone surfing etc. If it lasts significantly longer than the proper one I'll keep it in the phone..
