I finally got my sidekick. I got it free from the t-mobile store in the trafford centre after smiling nicely at the assistant. It's supposed to cost £50 on web and walk 100. It seems really good- the internet is quite fast, especially if you turn the pictures off and the email push is great. I keep thinking people are texting me all over the show but its my emails! The bad point I guess is the camera which is more pants than my sony ericcson (think its z600), which is quite old. But I have a digital camera anyway..so not that bad.
I've been looking for any tips and tricks on the internet but can't find any, so if anyone finds any please share! :)
