This issue started around 3 months ago, that everytime I try and install new apps, or search the internet my I Phone is so slow. Last night my new allowance started so I tried to download some free apps on my 3G network the apps where only small yet still they haven't even loaded yet.

When I try and search for apps my phone does nothing, unless I switch my phone off and on several times. I even recently had my I Phone 4 exchanged this helped a little but still it's driving me mad.

I live in West London is anyone else experiencing the same issue as me, and what should I do now?

I have done all the relevant updates and have the latest software with I Phone/I Tunes, Vodafone have checked the coverage in my area that's all ok, my phone isn't overload with music or pics or apps
