[Warning] Do Not Install MyWi 4.0 On iOS 4.2.1 (iPhone 4 will not boot)
Just a warning for you guys, I have just installed MyWi 4.0 on my iPhone 4 and it has stopped it from booting up.
Restore is required to fix this issue. So please wait for an update for MyWi 4.0. Follow @Intelibronco on twitter for updates or you may follow me and I will tweet the updates at @bhfboss
