I've experienced a similar issue sometimes when enabling data connection using apndroid (changing apn), I don't know what happens but I solve this by disabling e re-enabling again data connection (always through apndroid)
I just bought a used Defy for myself because I actually like my wife's Defy + CM7 better than my N1 with CM7. So I have two Defys, my wife's and mine, both are on nightly 2011-Nov-02 I believe now, and they both have connectivity issues with 3G, and yes I have used the baseband switcher on both. Here is some more detail:
To answer the first question from darmach: What is the purpose of the green color change? From what I can tell and from what I've read, the green color change is simply indicating that the phone has established a data connection (wifi or cell) with Google. It does not necessarily mean that data is not working. To confirm, simply sign in to Google Talk (start up the Talk app) and the bars should instantly change green when the connection has been established.
I have some logcat info from the RADIO logs that look interesting, I will make some comments on the logs and post them here.
Note that 2G seems to be working perfectly. I burned through my 3G 'fast' data allowance on O2 here in Germany so I switched the phone to 2G mode, and it has been working fine the last few nights going into and out of airplane mode.
i have the same problem. I've tried to flash CEE again and than CM but nothing changed.
Since I've returned from Germany and am back on T-Mobile in the US with the Defy, I have not had these issues. 3G connects all the time and I've even noticed improved battery life. This seems to be related to the SIM/carrier somehow.
@skelliam maybe in germany U have a better 3g signal, my phone hangs when i'm in low signal areas and than i have to reboot it...
I've not really seen the phone hang yet. As I mentioned, no issues at all here in the US. I did have the same issue here once, where there was no data connectivity and I could not get into airplane mode. I switched baseband twice and rebooted and this was resolved. So there is still something going on but it is not as easy to reproduce here in the US with my US Defy for some reason.
Same problem on a defy with CM7.2. Happens often in weak reception areas: when the phone is switched on it will initially make a "G" connection and be able to transfer data. Within a few minutes the phone is unable to access data or make calls, or enter airplane mode. "Network operators" in "Mobile networks" doesn't find anything. When I try to make a call, it sticks on "Dialling". Hanging up doesn't work, the green phone shows in the status bar with "Unknown 00:00". Dmesg shows various errors, from isl29030_get_avg_noise_floor and also AUDIO_DRIVER: Error codec_open-INVALID mode requested. Only a reboot restores connectivity.
This problem happens even when data is disabled: the phone will "crash" so that making calls fails, . But with data off I can hang up ok, although re-enabling data or entering airplane mode doesn't work.
I am encountering problems with network connectivity through both EDGE and 3G networks. It appears in different locations, on different versions on CM7 (always trying to stick to newest nightly, tried also "stable" release)
Its also not the device malfunction - a friend of mine with Defy on CM7 is encountering same difficulties.
At random wireless network "hangs" - icons are greyed out, and there is no network connectivity. Tried switching on and off internet APN, and airplane mode - it does not change anything, unable to switch on from airplane mode again.
Please look into this issue - for me it compromises whole android phone idea - i need to have mail synced, and gtalk online.
Also - when icons change to grey? What its exactly informing me about?I am asking because sometimes wifi is doing the same thing.
