I have two AT&T-locked Sony Tablet Ps. I remember from awhile back that it's pretty trivial to replace the miniPCI-e WWAN card with an unlocked one. However, the suggested card model is HSPA+ only. We just switched to T-Mobile and got two data-only SIMs as part of the deal, so we're more interested in using the Tablet Ps now with cellular.
Is it possible to upgrade to LTE with a new card? Has anyone done this? Thanks!
