Recently we came across FastRa1n which is advertised to untethered jailbreak iOS 4.3.5 and iOS 4.3.4. There are some sites on the Internet which are selling FastRa1n for around $30 promising the users that it can untethered jailbreak iOS 4.3.5 and iOS 4.3.4. Moreover it is also advertised that fastra1n, available for Windows (fastra1n.exe) and Mac (fastra1n.pkg) can unlock iPhone 4 on 02.10.04, 03.10.01 and 04.10.01 Basebands; iPhone 3GS Basebands – 05.14.02, 05.15.04, 05.16.01 and 05.16.02. All these information about fastra1n are fake and it doesn’t work as advertised.

The Dev-Team which usually releases jailbreak tools for iOS haven’t yet released any tool for untethered iOS 4.3.5 jailbreak and if you need an untethered jailbreak then you have to downgrade to iOS 4.3.3. So if you come across any site that promises you a tool to untethered jailbreak iOS 4.3.5 and iOS 4.3.4 on iPhone, iPad or iPod touch, just ignore it and wait until we hear about the updates from the Dev-Team.
