Consider yourself very lucky if you purchased Nullriver’s NetShare before it was pulled from Apple’s App Store.
It’s just that good.
Armed with this app, an iphone running 2.0+ firmware, a Windows XP laptop and Apple’s Safari Browser, you’re no longer constrained to a network of commercial hotspots and nefarious wifi connections.
Experience near-DSL speeds in 3G service areas, completely untethered from the wired world and costly data card contracts.
Proceed with caution.
Though this seems to work, understand you may be violating your carrier’s terms of service and possibly exceeding your bandwidth allotment. Use at your own risk.
Not so easy.
As great as the app is, it can be quite painful to get going the first time.
For those of you struggling with setup, I’ve laid out most of the key steps below. Not sure if this is the best way to setup, but I was able to configure three different laptops, so it is one way of doing it.
Hope this is of help to some of you and please sound off in the comments with stories of success, failure & why NetShare is almost as freeing as the Stadium Pal.
