Very good write up. Thank you for doing this.
As you mentioned, one area where Straight Talk could improve their website is their maps coverage. The "Androids" map coverage is laughably wrong. It's like they have not even thought about updating their maps from back when ALL their Straight Talk branded Androids ran on Sprint.
They need to trash that outdated "Androids" map entirely.
And even though the genius BYOP (Bring Your Own Phone) SIM plan is so totally different from the rest of Straight Talk, that it has its own URL -- StraightTalkSIM.com -- all the links are so intermingled with the "regular" Straight Talk website (and their outdated maps) that it's too easy to think if you are bringing your own state-of-the-art Android phone to Straight Talk it will have almost no coverage. On StraightTalkSIM.com, the "coverage" link at the TOP of the page is accurate for BYOP. The "coverage" link at the BOTTOM of that same page is for Straight Talk-branded phones only, not the BYOP. VERY confusing.
And it comes with the latest Android software from Google, 4.1 Jelly Bean while not many Android phones even have 4.0 ICS. Most Android phones still are running on 2.3 Gingerbread. The Galaxy Nexus has great specs, and the newest software -- and is still onlly $349. For an unlocked new Galaxy S III or HTC One X or latest iPhone you would be paying around $600 or more.
The Galaxy Nexus (< designed by Google engineers to be an Android showcase) still gives the newer Samsung Galaxy S III a run for the money:

However, while 3G Watchdog is good, in my opinion My Data Manger is better.
Shows you how much data you are using over mobile or wi-fi. Lets you set multiple alarms, daily and monthly, as you approach the limits you set. Lets you sync with your billing cycle. Shows you via chart, lists, graphs what is using the most data.
AND, if you wish, My Data Manager lets you set a self-governor so you don't exceed a certain level of data usage over mobile. If you desire, you can set a daily/monthly limit to automatically cut yourself off before Straight Talk throttles you. Others have said 3G Watchdog does not have that feature, and they have to download a 2nd app for that functionality. My Data Manager has it all.
