How to disable lock screen in ICS when VPN is set?

> **Possible Duplicate:** > [Connecting to VPN forces having secure screen lock](https://android.stackexchange.com/questions/22867/connecting-to-vpn-forces-having-secure-screen-lock) I have **Sony Xperia S** with ICS 4.0.4 stock rom **(rooted)**, I need to have a **VPN account** set in my phone, but when I add a VPN account, the phone asks me to set either a pattern or password for lock screen, which I don't want. Is there an app or hack **to disable lock screen** or at least, have just simple "slide to unclock" instead of pattern or password?
