MMs.apk stopped my Browser working

[Guest hp1]

I've been trying to get my Hero 2.1 on O2 Uk to receive full size MMS, I did this by spoofing the phone as an Iphone using an MMS.apk from XDA, it worked, fantastic, except bizarrely my browser wont load any webpages. My data connection workks absolutely fine with every other app that needs a connection, just not the browser. Any ideas folks?

Cheers
