I've had my C7 for about a month, and I really like it. In fact, I can't seem to put it down, and don't know how I managed without it (how siily!). At first the connection used to stick a bit, and I'd have to switch the phone off to get it moving again, but I have sussed that when using the email function, rather than backing out, choose OPTIONS and EXIT and it doesn't stick any more. Great! I also had problems then accessing my emails from my laptop, presumably as I was still logged in elsewhere. Since using the exit function, all this has been resolved. It does gobble battery power, but the power save function seems to really help this. I really like it!
