I hope you were just philosophising... Altough you could solve a block with your cellphone, you will break it in a very short time (the phone, not the block).
Chances are higher of winning your national lottery with buying just 1 ticket/week than actually mining a block with your phone... And if you win the lottery, you'll make a lot more money than you'll make by finding a block...
proof:

BTC/year
25/0.0000072 = 1 block every 3.472.222 years...
One block (preev rate) = 8.474$
So, given there is no halving, and no diff increase, it'll take you 3.5 million years to mine a block with your phone (on average)
The odds of winning euromillions:
1 in 116,531,800, giving you €46,720,282.16 (

Given that you play 1 ticket a week for 3.5 million years, you'll buy 182 million tickets... So you'll statistically win 1.5 times... Giving you 73 million...
These are you expected profits... the expected cost of 1 euromillions ticket is 2€... The cost of mining 24/7 with your phone is the cost of a new phone every couple of months + the cost of your electricity. Even tough there is no objective way to quantify this, i'm pretty sure it's higher than 2€/week
These are all averages offcourse... it IS possible you'll mine a block with your cellphone after mining 2 minutes, and it IS possible that you'll buy 1 lottery ticket a week for 10 million years without winning... These are just averages and odds Last sidenode: i'm not really a fan of gambling in any way, so i wouldn't suggest buying lottery tickets, nor would i suggest mining with your phone... But each to his own
