The Voyager is not an iPhone competitor.
A competitor phone would be a phone that has nearly identical features and a similar design. A competitor is also released and generally marketed as a "known" competitor.
Verizon Wireless has even stated (along with LG) that the LG Voyager was approved by the FCC about 5 months before the first iPhone...this means that even though the Voyager came out much later, it was in thought much before. Verizon Wireless also denies any claims that any phone will and can compete with the iPhone at this time.
The LG Voyager is exclusive to Verizon Wireless, but that's how most "nice" phones are. The Apple iPhone was originally going to be a Verizon device, but Verizon rejected it because Apple wanted nearly all profit.
