To those suffering from the SMS 'unread' bug in CF03, here's how to fix it:
1) Get yourself a file explorer that can overwrite ROM files. The file explorer that comes with the phone can't do this. I use
Resco Explorer, although you can also use
Total Commander (it's free!)
2) Download the SMSTrigger.zip file attached to this post, then save it to your phone
3) Using Resco or Total Commander or whatever you're using, extract the contents of the SMSTrigger.zip file to the \Windows directory ON THE DEVICE (not the \Windows folder in 'My Storage')
4) If all went as planned, you will get a warning to overwrite the SMSTrigger.exe file. Say 'Yes'
5) Re-boot and have someone send you a long messgage to test
Good luck!
