Noob Needs Help linking wifes Epic to Archos Tablet. And other things

[JohnMcD348]

OK, just bought the wife a Archos 101 G9 tablet yesterday and first thing I did was upgrade it to the ICS that was available. My wife has been using an Epic 4g(slider) from sprint now for about a year. I've really done nothing with it as I'm, more or less, a windows person.

Anyway. she wants to use the Tablet as a video viewer/movie watcher when on trips, on top of using it to continue with our son's education with online courses through his school. We had thought we'd be able to link her Epic w/ Gingerbread to the tablet with Ice Cream sandwich via either BT or WiFi tethering so her phone would act as the modem. I can't seem to make that happen. When both items are searching, niether one can find each other. i tried it with my WP7 HTC Arrive and they did find each other but could not link up due to incompatibility. the usual $20+ fee extra per month from Sprint would allow her to Hot Spot her phone but I was wondering if there was another option?

My WP7 phone doesn't allow tethering but I was hoping someone, somewhere might know of an app or other means, besides fully Rooting/jailbreaking/hacking(Bricking) her phone.

There will be other questions I'm sure coming in the next few days as my wife asks me to do other things to her tablet/phone. I appreciate any help you all can give me on this. I haven't checked out XDA or any other place yet.

Any and all help/insight is appreciated.

Thanks
John
