there was so much information here with so many updates here and there..I think if you invest a good amount of money on your phone -you deserve to at least spend 7 u.s. dollars or the equivalent in euros for a more grounded flashing system and wonton felt like the most up to date and reliable (thats not to say that they also don't have phones that have issues after using their service) but they were established. I also wasn't too familiar with flashing so I just wanted to get to the source and just get it done ..no downloading here for this and download another app for custom files.. Wonton did what it had to do in six minutes.. i would recommend it if you don't have time to get all the downloads of apps . but if you have the time and can spare your phone to experimenting thenthere are other apps here for you..
I'm not too famliar with Visata and honestly don't know if alot of the apps here will support Vista, it might be another reason to use wonton..buI'm also not sure if it also supports Visa??? just looked at their support site they do support Vista -http://www.wotanserver.com/Getting_Started_Guide.pdf
