According to research firm ComScore's latest report, Apple has reached the #2 spot on the list of most popular mobile phone makers, taking the slot previously held by LG. iPhone users now account for 17.8% of the U.S. mobile market, while LG tags close behind at 17.6%. Samsung still leads all other manufacturers with 26.3% market share, up from 25.6% just three months prior.

Apple's iPhone 5 and Samsung's Galaxy S III are likely the two biggest factors in both company's recent gains. Motorola and HTC both rank below LG on the list, accounting for 11% and 6.4% of the market, respectively.
