Betfair app on Sony Ericsson W995

Hi all..I was using a nice little app version of betfair mobile on my w995 until my phone broke..after fixing it and trying to reinstall the dinky little app that I'd been using, all I could get on my phone (after putting my phone number into betfair and being sent a text message) was a really nasty wap-like version on betfair nothing like the fruity little app I'd been used to, and it didn't allow me to actually install it as an app on my phone, each time I use it, i have to follow the link that i was sent from betfair...I've rang betfair and they basically shrugged at me down the phone.  Anyone know how I can get a version of betfair that I can actually INSTALL on my w995?.  The app version I installed was around 2011 time...Thanks in advance
