Blackberry apps problem?

[xXBuckThunderXx]

Sometimes my blackberry wont load apps like twitter, facebook, and blackberry appworld. It says that i need to connect to Wifi to use the app (While im already connected to Wifi) And it only works when i delete them and redownload them (which takes like 10 minutes to do) But after a day or so the apps stop working again... any help? Please dont say "Buy an IPhone or buy an Android"

I know there is a new BlackBerry app world about, have you tried downloading that? If that doesn't work then back up your phone, then restore it completely back to factory setting then give it another go. If that does not work, throw it out the window! I've had so many problems with my BlackBerry it's turned into a very bouncy phone lol. Hope this helps
