If you already own the Nexus 4 and has $US60 to spare Google Play offers a good deal for you - the new Qi wireless charging stand that potentially will double as the same recharging station for other mobile devices.

The dock appeared Monday on Google store and is initially available for buyers in the United States, according to Engadget, for $US59.99. No indication is provided at this point on when the orb-looking, cut in half, Nexus 4 accessory will be made available to international buyers.

Since this is a third party offering, though officially sanctioned by Google Play, the likelihood is high that other smartphone brands can be attached to the charger but Business Insider has no specifics if the tool can be paired with Nokia's Lumia 920 for instance.

Regardless, the Qi charger will function quite efficiently when partnered with a battery widget app (check the image provided by Google) that Pocket Lint said can be purchased on Google Play for only $US2.

And as the global distribution of Nexus 4 further improves, sellers continue to package the LG-manufactured handset in attractive deals. T-Mobile and U.S. giant retailer Walmart now sell the powerful Android device for only $US148.

The whole purchase will allow buyers to take home a 16GB Nexus 4 with all the published specs plus a two-year contract from T-Mobile. The discount is significant considering Google sells the phone of the same model for $US349 while other retailers jack up the sticker price really high.

Proof of that is Walmart's retail pricing where the contract-free Nexus 4 is bearing this tag: $US550, according to Gotta Be Mobile.

Incidentally, the same Walmart-T-Mobile arrangement also applies for Samsung's Galaxy Note 2, this time for $US278. Consumers will get a white version of the popular Samsung phablet plus a two-year network access courtesy of T-Mobile.

Manufacturers and sellers have been spicing up and lowering the price marks of numerous gadgets in this time of the year, a collective approach that analysts said was meant to maintain buyers' interest with device models that were up for replacement.

Such view is true for the Galaxy Note 2 as its better sibling, the Galaxy Note 3, is reportedly due to arrive later this month. Does it follow that Google and LG are mulling a refresh of Nexus 4 anytime soon?
