[Dell Streak 7] jiwengang:
One issue:

which may already around since 2.2.2 upgrade, but I am wondering if Steve has any ideas about it.

Basically if I left the HSPA connection idle for a while, (20 mins or so with screen off), when I re active the screen, the signal bar just display as a cross with grey bar (indicating no signal) or airplane mode sign.

No matter how I on/off airplane mode then, the signal bar wont give a **** about it. basically that section looks totally frozen.

I went to APN settings, none of them are there.

The only solution now, is to reboot the device.

And it won't happen when I am charging the device.

It appears very often now. Again, really would like to hear any ideas about this issue.

Here is some of the log I thought is relevant.
