Reuters is reporting that sometime this summer Verizon Wireless will join AT&T in killing off unlimited data plans for all smartphones, including Windows Phone, Android, the iPhone 4 and upcoming iPhone 4S / 5. 

If true, the transition could go one of two ways:

Verizon could, like AT&T, offer two options, one relatively inexpensive with a ridiculously low data cap, and one basically the same cost as the previous unlimited plan but with a new 2GB monthly limit.  Or, they could do something truly competitive and offer say 200MB for $5 per month with several tiered options up to a maximum limit of, say 4GB, that still costs less than the current $30 unlimited plan. 

We’ll let you guess which they’ll choose.  In any case, it looks like with this move by Verizon and AT&T’s purchase of T-Mobile, unlimited smartphone data will soon be a thing of the past.
