So, I think the 3G is killing you, try to use 2.5G like me and change to 3G only if you need it. If someone call you over skype while you are on 2.5G you can tell them you will call on a minute, then you change to 3G (with the applet is quicker) and call over 3G, then switch back to 2.5G when you finish. It may seem annoying but is one option.
