Unlock Dell Streak without another carrier's SIM card
The last time we checked in on Dell Streak Unlocker, a piece of $29 software that can unlock a Streak in minutes, it required the use of a non-original SIM card. Without another carrier's SIM inserted into it, the device wouldn't prompt you for the unlock code provided by the software. And without being able to input the code, you obviously couldn't unlock the Streak.
This may not sound like much of an issue since most people who want to unlock their devices already have another carrier's SIM on hand, but what about those who don't?
Thanks to version 1.30 of Dell Streak Unlocker, if you're about to travel to another country and you don't already have the SIM card you'll need there, you want to increase the resale value, or you just want to have other carrier options for the sake of having them, you can now unlock your Streak without needing another SIM. The unlock code prompt is automatic.
This is great for everyone but is especially useful for owners of the Softbank Streak in Japan. This particular Streak variant doesn't acknowledge the presence of a non-Softbank SIM and therefore won't ask for an unlock code, which some believe is the carrier's way to prevent customers from unlocking the device. The only way around this in the past was to root and flash a custom ROM, which isn't something that all users want to do; version 1.30 solves this problem and makes unlocking easy for everyone.
Whatever your reason for wanting to do it, unlocking your Streak is a simple and now SIM-less process that begins at the link below.[Dell Streak Unlocker]
