Yesterday the application was released for delivery on iTunes and within hours of availability was removed by Apple.
To be honest, this comes of no surprise, what is surprising is that Apple allowed it to be available at all - but even more surprising was when the application became available again later in the day.
And was then subsequently pulled again.
Nullriver has yet to receive any comment from Apple as to the reason the application has had yo-yo-like availbility, stating this on the company's web-site:
"Update: NetShare is now back up and available from the AppStore! We're not quite sure why Apple took down the NetShare application yet, we've received no communication from Apple thus far. NetShare did not violate any of the Developer or AppStore agreements."
"We're hoping we'll get some feedback from Apple today. Sorry to all the folks that couldn't get it in time. We'll do our best to try to get the application back onto the AppStore if at all possible."
"At the very least, we hope Apple will allow it to be used in countries where the provider does permit tethering."
The statement was then updated at a later point, with the brief comment:
"Update 2: Apple has taken it down again, with no explanation yet again."
Macrumours has an interesting forum post stating the list of pulled applications from iTunes.
