South Korean mobile phone maker LG Electronics launched on the market, during the first quarter of the ongoing year, one of its most appealing touchscreen mobile phones, the LG Arena. The handset, which came to the shelves as a high-end feature phone, is now rumored to already have a successor under development in LG's labs.

According to a recent post on Cellpassion, a post on the Wi-Fi Alliance shows that a higher-end variant of the LG Arena has just received Wi-Fi certification. All that it is known for the time being about the handset is that it features the model index LU9400, and that it has received the Wi-Fi Interoperability Certificate on November 20, this year.

Based on the success the LG Arena already registered on the market, it would make a lot of sense for the South Korean handset vendor to think about delivering a better successor for the handset. However, it remains to be seen what exactly this phone will come to the market with in terms of display size, processor frequency, camera quality, software solution, and so on.

Since no details other than the Wi-Fi certification are known at the moment, the guessing area is opened to anyone, but we'll be waiting for additional info on the phone to surface before walking that road. However, it won't be a surprise if the said LG Arena Max will come to the market with a larger touchscreen display (a trend for high-end phones these days) or will prove to be a smartphone.

One way or the other, it might become a popular handset too, following the success of its predecessor. The LG Arena was sold in more than 1 million units by August 2009, about half a year after it got launched, and is already available in a wide range of markets around the world, in various color versions.
