I just rooted by AT&T Galaxy S2 (SGH-i777) to troubleshoot battery usage. I also would like to tether my laptop (OS X Lion) to make use of my phone's data connection intermittently while traveling.
I see both "USB tethering" as well as "portable WiFi hotspot" under
Settings --> Wireless and network --> Tethering and portable hotspot. Should I use this feature or install an additional tethering application?
What [if any] are the advantages of a separate tethering app over the built-in tethering controls?
