I appear to have lost both 2G and 3G data access (HTC Hero, android 2.1, O2 UK carrier) - specifically internet browsing, gmail/gcal sync and MMS messaging. Things work OK on WiFi. Phone & texts work OK anyway. I am not aware of having done anything. The APN settings are: Name: O2 Postpay APN: wap.o2.co.uk Proxy: 184.108.40.206 Port: 8080 Username: o2wap Password: password Server: not set MMSC: http://mmsc.mms.o2.co.uk MMS port: 8080 MMS protocol: WAP 2.0 MCC: 234 MNC: 10 Authentication type: None APN type: * I tried a factory reset - made no difference. Can anyone suggest what can take out 2g & 3G data simultaneously?
