My3G causing phone to hang on apple logo straight after install???

[Ricer]

Have been using My3G with no problems whatsoever for about 2 months now, currently Im waiting on an official unlock to come via Apple & I restored the phone to 4.0.1 using Umbrella the other night with no problems, even got My3G installed again & everything was fine but the unlock had not yet come through

Then today I restored again, everything was fine till I went to reinstall My3G....after jailbreaking I went through the usual process in Cydia, the loading screen fires up & then asks me to reboot device, when I do the phone switches off, loads up the apple logo & then just hangs on that

iTunes can still see the phone & even tries to sync with it but the apple logo just still remains on the phone.
I thought maybe it might justve been a dodgy install so tried again, but now after the 4th time of trying it keeps doing the same thing...I even tried restoring from a different backup before jailbreaking but still that has made no difference

Has anyone experienced anything like this?
Im headed away on vacation soon & was depending on this to use Facetime to stay in touch with people at home so its important I get it working

All is good after JB (iPhone4 ios4.1 limera1n)
EXCEPT iPhone hangs at Apple logo on reboot after install of My3G.
