I would recommend a Non camera Nokia e51 combined with the third gen iPod touch. Install joikuspot on the e51 and together with a mobile data plan, u can turn your e51 phone into a router whenever u need it. The iOS platform is fantastic for surfing the web and other miscellaneous online stuff like Facebook. Both products are no longer in production but u can buy them from second hand shops or online forums where people may sell them.
The other option would be getting a non camera blackberry. This is a one device solution. However I find the blackberry's Internet browsing capabilities inferior to ios's.
