Heh.  I suspect it's not network related.  I've got one of these and
I've been through all of it.  While upgrading to Froyo makes the
device a little better in some ways, the problem you're running into
is I/O (disk) related.

Specifically, the filesystem used for /data, /datadata etc on this
device is not the traditional JFFS2, but rather a proprietary, awful
thing called RFS.

Short answer:
1. Install "ROM Manager" (you may already have done so) from the Market.
2. install the voodoo kernel/lagfix from http://project-voodoo.org/
3. Drink.

More info why RFS is cancer and you need to get rid of that immediately:

I couldn't be happier with the SGS after installing the voodoo kernel
and a 2.2 image (I'm using one of doc's ROMs), but I wouldn't
recommend it to anyone given that it comes from the factory with such
all-embracing fail.
