Thread: Can't download apps

Got a HTC Tattoo 5 days ago and thought it was awesome. Went onto Android market and downloaded a few apps no problem. Then went to download another yesterday (BBC Sport news app) and it won't download. I tried several other apps and all would not download. The download process starts just never finishes so I cancel the download. Checked my account with regards to internet useage and Vodaphone said it shouldn't be a problem. Signal strength very good. Took battery and sim card out then replaced it but still no joy. They say unit may be faulty?
Can anyone help. Thanks
