3G is a great selling feature for modern mobiles, but are many people really using these 3G features yet? I certainly don't - I moved to Virgin Mobile when I got my K800 and unfortunately mobile web browsing is now too costly at £4 per Mb (with no option to add GPRS bundles), and I don't know anyone I can make video calls to yet. Another grumble I had after changing phones was battery life on my new phone was a bit disappointing. However, through a colleague at work I made a nice discovery - disabling the 3G features on your K800 can extend your battery life for another 24 hours. This is how you do it:
Menu - Settings - Connectivity - Mobile Networks - "GSM/3G Networks"
Change the option from "GSM and 3G" to "GSM Only".
The 3G icon will then disappear from your standby screen. You can always switch this back when needed or if all of your friends suddenly go out and buy video phones!
