It’s been less than ten days since Apple released iOS 4.3 for the iPhone bringing WiFi tethering, improved Safari speed and other goodies and it looks like iOS 4.3.1 might be on its way, according to recent rumors.

According to BGR, the platform refresh will contain minor bug fixes and it is due to hit in the next one or two weeks. There will be a baseband update for the iPhone 3GS as well as fixes regarding memory freeze upon reading large files from USIM file system in addition to fixes related to NTLM authentication in apps and on websites. No other information is available at the moment, neither regarding a certain date — hopefully if will not be the only thing announced at the April event for MobileMe — nor related to Verizon iPhone compatibility.
