I just thought I'd draw attention, in here, to an exciting development by alcurtis93, over in XDA, in developing a CWM-flashable Orange UMA Signal Boost app for SGS2s running an ICS-based custom ROM on a Syiah kernel. Note that it only works for UK Orange subscribers. The thread is here
[CMW ZIP] Orange UK ICS Signal Boost - xda-developers
Not having Signal Boost was the only thing tempting me to install a stock Orange ROM. We don't have a strong signal in some rooms and our best friends' house has no signal at all. Thanks to alcurtis93 I can now stick with my Resurrection Remix v1.9.1
