OK i have an 02 Ireland iPhone running on the Vodafone IRL network was running fine and anytime i went to the UK or France i could connect to Vodafone Uk etc.

Had a boot loop problem a couple of weeks ago that could only be solved by custom firmware, the custom firmware i downloaded said it was already activated(if that makes any difference)

It installed fine i ran blacksnow to allow me to use my vodafone sim and ran the restore of my old files etc all fine

However i went to the UK last week and could not connect to Vodafone UK or any other network when i selected carrier settings it gave me a list of availible netowrks - Orange,Tmobile and Vodafone.

But when i tried to connect to any of them it would give me:

NETWORK LOST - your selected cellular network is no longer availible.......

Any ideas
