I have a much cleaner... easier solution!
Just take the $360 (one year at $30/month) and hit the roulette table.
Put it ALL on black. If it hits, you now have 1 year's worth of 3G.
If it misses, just put another $720 on black to get that loss back, plus 1 year's worth of data.
If it misses again, just put another $1440 on black.
Then you'll be able to recoup the $1080 you lost plus have a year's worth of 3G!
If it misses again, well put another $2880 on black.
Then you'll be able to recoup the $2520 you lost plus, you'll have a year's worth of 3G!
<repeat pattern until you have that $360 in profit>
Do again next year.
This plan is flawless. Eventually it will hit.
What could I possibly be missing with this plan??
