Palm have "politely" warned the Pre homebrewers behind the Pre Dev Wiki not to talk about hacking the handset for internet tethering on their site ... because Sprint might complain.
The caution from Palm suggests that 'they' don't have a problem with someone figuring out a tethering solution for the easily hackable handset, but that Sprint - who don't allow tethering, even on their $99 everything plan - might.
Palm warned that if Sprint complained, they would be forced to react against the people running the site with legal action. As a result the guys at Pre Dev Wiki have pulled any tethering chat and posted an explanation as to why it has gone.
We have been politely cautioned by Palm that any discussion of tethering during the Sprint exclusivity period (and perhaps beyond-we don't know yet) will probably cause Sprint to complain to Palm, and if that happened then Palm would be forced to react against the people running the IRC channel and this wiki.
They have however, added a note stating that Sprint does not have a Pre plan which allows tethering under the Terms Of Service. It seems like everyone involved is sticking a finger up at Sprint, though not necessarily to their face.
