New SDK 3.2 beta 5 shows pointers that there will be a 3.2 Firmware for the iPhone and iPod Touch. Looking thru some Plist files we see some capability lists and marketing names. iPhone and iPod Touch are listed.
Also there is the standard Apple ringtone, and ringtone changed sound. What this means to us is that 3.1.3 was just a fishing game from Apple to see if the Jailbreak Dev teams were going to let loose any new exploits. And that Firmware 3.2 for the iPhone and iPod Touch may be coming when the iPad ships, if not sooner.
This doesn’t look like it pertains at all to the iPad, so don’t get your hopes up.
