Can't download apps on iphone by wi-fi. HELP!!

[bluewomble88]

I've been trying to download a couple of free apps on my iphone 3gs over a wi-fi connection in my home as they are over 10MB and so I can't use 3G. However, when I try it just says "An unknown error occurred". No matter how many times I retry or try other apps I get the same problem.
How do I fix this??

How much space is left on your flash drive? Have you tried rebooting the phone and then downloading?

I have well over half of my space left on the device. I have tried rebooting the phone but I still get the same error.

How's your wifi connection?

Connection is full strength and the device works perfectly when watching Sky Sports etc.

Turn off Bluetooth and try again. I get horrible wifi service with BT on my GS.

IDK what to tell you, unless it is the app store causing the problem.
