I'm having a real problem trying to get the CellId. And I'm not sure where the problem is, but I keep getting a zero. I certainly can get the IMEI via CTelephony, so I know that I'm accessing CTelephony ok. Now I'm thinking it's got to do with the UID I'm using and getting it signed. I can only use open signed online, but everything I tried has the same old problem. And I know it's not my phone, which is an E65 incidentally, as I installed another app which reports back the CellId just fine. Does anyone have any thoughts?
