there appears to be a bug in lwip that causes Xell to crash when requesting an IP on a network with multiple DNS servers defined in the DHCP config,
https://github.com/Free60Project/xell-reloaded/issues/8
if somebody could build a TRINITY_RGH3.ecc or updxell.bin
with this patch
https://github.com/lwip-tcpip/lwip/commit/1eeb70fbfab284054da4a3bc96d366eac77c4c2a
applied, I'd be happy to test it.
